Question

Which one of the following compounds will not undergo aldol condensation ? (A) Acetaldehyde (B) Formaldehyde (C) Propionaldehyde (D) Acetone

Tardigrade Admin · Accepted Answer

Aldol condensation is given by only those aldehydes or ketones which contain at least one α- H atom. Hence, formaldehyde, HCHO due to the absence of α - H atom, does not give aldol condensation.

Q. Which one of the following compounds will not undergo aldol condensation ?

Acetaldehyde

Propionaldehyde

Acetone

Aldol condensation is given by only those aldehydes or ketones which contain at least one $α - H$ atom.

Hence, formaldehyde, $H C H O$ due to the absence of $α$ - $H$ atom, does not give aldol condensation.
